It is the principal object of the present invention to provide an improved hand-operated marking device.

Furthermore, it isan object of the present invention to provide a novel means for adjusting of the setting of the indicia to i be printed by the device'on the outside thereof.

Another object of the present invention is to provide a device of this kind which is self-inking.

A further object of the present invention is to provide a sim ple study and practical article of manufacture which can be economically produced.

Various further and more specific purposes, features and advantages will clearlyappear from the detailed description given below taken in connection with the accompanying draw ing which forms part of thisspecification and illustrates merely by way of example one embodiment of the device ofthe invention.

BRIEF DESCRIPTION OF THE DRAWING In the following description and in the claims, parts will be identified by specific names for convenience, but such names are intended to be as generic in their application to similar parts as the art willpermit. Like reference characters denote like parts in the several'figures ofthe drawing, in which:

FIG. I shows a side view of the device;

FIG. 2 shows a front view of the device partly in section;

FIG. 3 shows an enlargement of the arrangement of the printing wheels and of the wheel-setting facilities in a section taken along the line 3-3 in FIG. 2; and

FIG. 4 shows the face view of the transparent cover.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now in more detail to the drawing illustrating a preferred embodiment by which the invention may be realiz ed, there is in FIGS. 1 and 2 a hand stamping device 10 which has a lower, or stationary frame 11 and an upper, or movable frame 12'. Both frames 11 and 12 are substantially U- shaped, and have horizontally oriented upper bridge parts '13 and 14, respectively. Frame 11 has a substantially rectangular bottom frame 15 which holds the frame walls 11 and 11" together. Bottom frame 15 is covered with a layer of rubber 16 for protecting the articles to be marked with the device from being scratched or damaged. Vertically arranged slots 17', 17'' are provided in frame walls 11' and 11". A vertical tubular shaft 18 is mounted on top of bridge 13.

Frame 12 has a hollow shaft 19 mounted on top of bridge 14, which shaft 19 is closed on one end by a hand knob 20. A compression spring 21 is located in-shafts I8 and 19 so that shaft 19 which can telescopingly glide over shaft 18, will return to its initial position after a stamping operation has been performed. A horizontal shaft assembly 22 is rotatably located in the walls 12' and 12" ofmovable frame 12, and the end parts 23 and 24 ofsliaft assembly 22 are glidingly guided inslots 17'. I7".

The shaft assembly carries a plurality of type wheels 25 (five are shown by way of an example in the drawing) and an equal plurality of dial disks 26. This is shown in an enlarged scale in FIG. 3. The shaft assembly consists of an inner shaft 27 which is substantially solid and which has a threaded axial hole 28 on one end. A plurality of hollow shafts (five shown in the drawing) 29, 30, 31, 32. 33 are rotatably and concentrically fitted on shaft 27, each one of the hollow shafts carrying a corresponding type wheel. The hollow shafts extend through slot 17' of frame 11' and are rotatably journaled in frame 12, and each one of the hollow shafts carries a dial disk outside of frame 12 corresponding to one of the plurality of type wheels 25; that is, shaft 29 carries type wheel 34' and dial disk 34", shaft 30 carries wheel35' and disk 35", shaft 31 carries wheel 36' and disk 36", shaft 32 carries wheel 37' and disk 37" and shaft 33 carries wheel 38' and disk 38". Shaft 27 has a small flange 39 at the one end where threaded axial hole 28 is located, and has a spring washer 40, plain washer 41 and snapring 42 on the other end. By this structure the entire assembly 22 is kept together under a certain amount of friction caused by the pressure of spring washer 40, resulting in a kind of clutch action on the dialing device.

Each one of type wheels 34', 35, 36', 37 and 38' has a band 25' made of rubber or other suitable material mounted thereon in tire fashion. The bands 25' carry the printing indicia on the surface thereof in conventional manner and may be interchangeable. The corresponding dial disk 34", 35", 36", 37" and 38" carry correspondingly printed or engraved indicia on the ring face, as shown in FIG. 1. Furthermore, each one of the disks has a pinhole 43 for dialing. Dial disk assembly 26 is covered by a transparent cover 44 made of plastic or other suitable material which is rotatably held in place by a screw 45 which fits in threaded hole 28 of shaft 27. Cover 44 has a row of radially arranged holes 48 which match exactly dialing holes 43 in the disks. By inserting a pin through one of holes 48 in cover 44 and releasing the clutch action by pressing shaft 27 against spring washer 40, the corresponding dial disk with its type wheel can be readily adjusted.

Anink pad is swingably arranged on a pivot pin 47 in frame walls 11 and 11" and is linked in the well-known conventional manner (not shown in FIG. 1) with movable frame 12 so that it is in the inking position when movable frame 12 is in the released upper position'and is swung out of the path of the printing wheel'assembly when the downward stamping movement is performed (shown in dash-dotted lines).

While the invention has been described and illustrated with respect to a certain preferred example which gives satisfactory results, it will be understood by those skilled in the art after understanding the principle of the invention, that various movable frame and slidable axially on said vertical stationary shaft in telescoping engagement therewith; spring means abutting one end of said stationary shaft and extending within said hollow shaft for urging said movable frame to a retracted inactive position directed away from said stationary frame; a horizontal shaft supported by said movable frame for movement therewith and for limited axial movement thereon, said horizontal shaft extending from said movable frame; a plurality of hollow shafts mounted concentrically and rotatably on said stationary shaft; a plurality of wheels each securedly fixed to one of said hollow shafts within said movable frame; typecarrying means on each of said wheels; substantially planar dial disks mounted respectively on each of said hollow shafts and carrying indicia along an annular surface on the face of said disk, said dial disk being mounted on the outside of said movable frame at one side thereof and lying against a face of the neighboring disk, each disk having an opening so that said disk is rotatable through means inserted into said opening; and frictional locking means mounted on said horizontal shaft for preventing rotation of said hollow shafts and said dial disks when in locked position, said locking means being released through application. of axial pressure at one end of said horizontal shaft to axially move said horizontal shaft whereby said dial disks are rotatable to predetermined positions when said locking means is released.

2. The marking device as defined in claim 1 including a rotatable transparent cover on said horizontal shaft and having a plurality of openings corresponding to the openings in said disks, said annular surface on each ofsaid disks being visible through said cover.

3. A marking device according to claim 1, and in inking pad swingably arranged in said stationary frame, said pad abutting against said type-carrying means in said retracted position of said movable frame and adapted to swing away from said typecarrying means in said operative position of said movable frame.
